JAMES A. MCCOY, OF WEST SOMERVILLE, MASSACHUSETTS, ASSIGNOR T0 NATIONALELECTRICAL ADVERTISING (30., OF EVANSVILLE, INDIANA.

ADVERTISING- DEVICE.

Specification of Letters Patent.

Application filed September 23, 1909.

To all whom it may concern:

Be it known that I, JAMES A. MCCOY, a citizen of the United States,residing at WVest Somerville, in the county of Suffolk, State ofMassachusetts, have invented certain new and useful Improvements inAdvertising Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to advertising devices and particularly to thattype adapted to successively display to view a plurality of advertisingsheets mounted upon an intermittently operated endless carrier.

The invention consists in the details of construction and in thearrangement and combination of parts to be hereinafter more fully setforth and particularly claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which,

Figure 1 is a side elevation of an advertising device constructed inaccordance with the invention the top portion of the casing being brokenaway and one entire side removed; Fig. 2, a front elevation of afragment of the device, the front of the casing being removed.

Referring to the drawings A represents generally the casing whichcontains the mechanism of the device. Said casing is formed of the frontand rear members 1 and 5 respectively; side members 6 and 7; a bottom 8and a top (not shown). The front member 4 has an opening 9 formedtherein in which is mounted a pane of glass 10 to render visible theadvertising sheets which are contained within the casing. A shaft 11 hasits ends journaled in the blocks 12 and 13 which are secured to the sidemembers 6 and 7 respectively.

Mounted in a fixed manner on the shaft 11 at suitably spaced points arethe sprocket wheels 14 and 15 and similar sprocket chains 16 and 17travel on the sprocket wheels 14: and 15 respectively. Horizontallydisposed between said sprocket chains 16 and 17 with their terminalsforming the alternate pivot pins of the links of each respectivesprocket chain are the supporting rods 18. By thus utilizing thesupporting rods 18 to form alternate pivot pins on the links of thesprocket chains 16 and 17 it will be readily seen that not only is amore compact structure had but the necessity for providing an additionalsupport on said chains for the supporting rods 18 is obviated.

Loosely suspended from each supporting rod 18 through the medium of theclips 19 is an advertising sheet 20, the sprocket wheels 1 1 and 15, thesprocket chains 16 and 17 and the supporting rods 18 constituting anendless carrier through the medium of which the advertising sheets arecontinuously supported and carried and successively disposed in linewith the glass pane 10 so as to be visible from without the device.

In order to prevent the advertising sheets 20 from falling at irregularintervals to a depending position in front of the pane of glass 10 thereis provided a presser roller 21 which has provided at spaced pointsthereon the circumscribing flanges 22 formed preferably of rubber, orother elastic material. The roller 21 is fixed to a shaft 23 which hasits respective ends mounted for a rotatable and slidable movement ingrooves 24 provided at corresponding points in the side members 6 and 7of the casing. 'Said grooves are formed by securing to the side members6 and 7 a pair of cleats 25 and 26 in spaced relation to eachother.These cleats 25 and 26 are so disposed that the grooves 24 formedthereby will be located in alinement with a radius of the sprocketwheels 14 and 15.

Loosely mounted on each end of the shaft 23 are the collars 27 and 28,while corresponding collars 29 and 30 are loosely mounted at the ends ofthe shaft 11. Connecting the collars 27 and 29 is a coil spring 31, anda similar coil spring 32 connects the collars 28 and 30; said coilspring serving to press the roller 21 firmly against the advertisingsheets and thus preventing said sheets from falling at irregularintervals to a depending position in alinement with the glass pane;

From the construction previously described it will be obvious that arotation of the sprocket wheels 14 and 15 will cause the sprocket chains16 and 17 to travel in unison and result in the advertising sheets beingsuccessively disposed in a depending position in alinement with theglass pane 10.

The mechanism for imparting an interrock arm 33 is a ratchet wheel 35and a" pawl 36 is pivoted to the rock arm 33 and has its free endadapted to engage the ratchet wheel 35 during the movement of said rockarm in one direction.

Mounted on the bottom 8 of the casing of the device is a motor 37 whichoperates a diminishing train of gears 38, 39 and 40. The shaft 41 uponwhich the gear 40 is mounted also carries a disk 42 which haseccentrically pivoted thereto one end of a link rod 43, the other end ofsaid link rod being in turn pivotally connected with the rock arm 33. Itwill thus be obvious that when the motor 37 is operated the rotation ofthe disk 42 will cause a reciprocation of the link rod 43 which byreason of its connection with the rock arm 33 will cause said arm torock upon the shaft 11 and result in an intermittent movement beingimparted to the sprocket wheels 14 and 15 by reason of the engagement ofthe pawl 34 with the ratchet wheel 35 and the sprocket chains 16 and 17will in turn be moved so as to cause the advertising sheet 20 to fall ina depending position opposite the glass pane 10. Any backward movementof the shaft 11 and the sprocket wheels 14 and 15 is prevented throughthe medium of a pawl 37 which is pivoted to a cleat 38 secured to a sidemember of the casing; the free end of said pawl being in engagement withthe ratchet wheel 35. In order to vary the length of movement of therock arm 33, the link rod 43 has its upper end detachably said movementwill be decreased.

Vhile one particular form of the invention has been shown and describedit will be noted that various changes in the details of construction andin the combination of parts may be resorted to within the scope of theclaim without departing from the scope thereof.

lV hat is claimed is An advertising device comprising a casing, a shaft,an endless carrier mounted on said shaft, a series of advertising sheetshung on said carrier, a collar loosely mounted on each end of said shaftand disposed between the carrier and casing, a rotatable shaft mountedin said casing for movement toward and away from the carrier, a rollermounted on said shaft, a collar loosely mounted on each end of saidshaft and disposed between said roller and the adjacent side of saidcasing, a tension spring having its terminals secured respectively tothe collars disposed on corresponding ends of the roller shaft and thecarrier shaft constantly tending to move said roller shaft toward thecarrier to force the roller carried thereby into engagement with saidcarrier and means for intermittently moving said carrier.

In testimony whereof, I affix my signature, in presence of twowitnesses.

JAMES A. MoCOY.
